用800 nm激光激发，测量了Er ~（3+）-Tm ~（3+）共掺碲酸盐玻璃和碲酸盐光纤的可见和近红外发射光谱。在24 cm长的0.2wt%Er2O3和1.0wt%Tm2O3共掺杂碲酸盐光纤中记录了从1.35 μ m延伸到1.6 μ m的宽发射，半高宽（FWHM）类似于160 nm。Er ~（3+）和Tm ~（3+）之间的能量传递在发光机理中起重要作用。这些结果表明，Er ~（3+）-Tm ~（3+）共掺碲酸盐光纤有望成为波分复用（WDM）传输系统的宽带光源和宽带放大器材料。(C)2004年美国光学学会。
The visible and near infrared emission spectra of Er3+-Tm3+-codoped tellurite glasses and fibres were measured with the excitation of an 800 nm laser. A broad emission extending from 1.35 mum to 1.6 mum with a full width at half-maximum (FWHM) of similar to160 nm was recorded in a 24 cm long 0.2 wt% Er2O3 and 1.0 wt% Tm2O3 codoped tellurite fibre. Energy transfer between Er3+ and Tm3+ play important roles in the luminescence mechanism. These results indicate that Er3+-Tm3+-codoped tellurite fibre could be a promising material for broadband light source and broadband amplifier for the wavelength-division-multiplexing (WDM) transmission systems.
